Fill your pot with seed compost, leaving a couple of centimetres below the rim. Scatter the seeds evenly over the compost and cover with vermiculite. Water well, then cover the pot with a plastic bag or piece of clingfilm to keep the compost moist.
Remove the cover from the pot when seedlings appear. If growing your tomatoes on a windowsill, turn the pot regularly to prevent the plants growing towards the light and becoming distorted.
